Vaillant F.22 error help

Maresh · Oct 14, 2019

Hello,

My vaillant is displaying th error code F.22.
I did some research and apparently it is necessary to increase the pressure but I don't know how to do it.

kind regards

Kein Wasser means No Water. The water pressure needs to be in the green zone on the dial and between 1 and 2 bar. Pictures 2 and 3 are the gas meter you don't need to touch that. Its the water pressure that has dropped. There should be a fill loop from the mains water with a valve to open somewhere near the boiler.

Thanks for your help but I don't know where it is, it's not in one of the pictures ?

Someone familiar with this boiler will have to help here. I think the centre valve is the filler but appears to be turned on. I have a feeling there is another valve to open somewhere to allow it to fill the boiler.

Have a look at the manual here.

Sorry just realised doesn't have filling instructions.

Picture of directly underneath might help. It's badge up as an amtoTEC Plus but it looks loosely based on what Vaillant called a TurboMax Plus in the UK - on that particular boiler there was an integrated filling loop that you used a little Vaillant Key with underneath.

You will need a flexi filling loop and your filling loop is just below your boiler the connections with the caps on
